Cdr King TT520 Flash Unit, Optical Slave and Recycle Test, Godox rebrand

I. Slave mode response

First up i tested the optical slave on the TT520 flash and check how it performs. the TT52o is set to "s1" mode, on this mode it will respond to any quick burst of light. the trigger is a Nikon sb28 unit set on repeating flash.

First on 20 flashes @ 10hz

Then on 20flashes @ 20hz

II. Recycle time

After that I tested the recycle time of the TT520 on full power. the TT52o is set to "s1" mode, on this mode it will respond to any quick burst of light. the trigger is a Nikon sb28 unit set on manual 1/64 power.

So far so good, works flawlessly. I like the response time of the slave (s1) and can keep up with the sb28 repeating flash as well as the 3 second recycle time on full power. I will be testing this flash on the field and see how it performs on an actual shoot.

More to come.
